摘要

考虑了一种利用发射的水平极化信标信号确定飞机俯仰角的偏振调制方法。置于机载接收天线微波信道中的偏振调制器为接收到的信标信号偏振面的法拉第旋转器。俯仰角由偏振面旋转频率的二次谐波相位决定，该相位包含在接收机输出信号的包络谱中。描述了实现该方法的实验装置的原型。给出了飞机俯仰角的测量结果，并对测量精度进行了估计。

A Method for Determining the Aircraft Pitch Angle in Radio Beacon Navigation Systems

A polarization-modulation method for determining the pitch angle of an aircraft using emitted horizontally polarized beacon signals is considered. The polarization modulator placed in the microwave channel of the airborne receiving antenna is a Faraday rotator for the polarization plane of received beacon signals. The pitch angle is determined by the second-harmonic phase of the polarization-plane rotation frequency, which is contained in the envelope spectrum of the receiver output signal. A prototype of the experimental setup implementing this method is described. Results of aircraft pitch angle measurements are presented, and the measurement accuracy is estimated.
